     Then only one possibility is to write your own keyboard handling
program (a'la KEYB or MKEYB), which replaces BIOS handling routines
(Ctrl-Alt-Del handled by BIOS) and also substitutes Ctrl-Break handling
(through INT1B and INT23), because "break off" (which calls INT21/33) turns
off handling ^C/^Break only for file operations (character IO functions,
like INT21/01, always checked for ^C/^Break).

     Modifying DOS sources for this, I think, is unwise.
